摘　　要：采用PCR检测方法，对华东北部地区禽肿瘤病进行流行病学调查，调查鸡群为琅琊蛋鸡、海兰鸡、AA肉鸡、艾维菌鸡，调查无症状鸡样品600份，调查有症状病鸡样品200份。调查结果表明，无症状鸡马立克病感染率为3．3％-4．4％，有症状病鸡马立克病死率为70．9％～813％；无症状鸡禽白血病感染率为8．3％-11．6％，有症状病鸡禽白血病病死率为4．4％～6．6％无症状鸡网状内皮组织增生症感染率为4．3％～5．5％，有症状病鸡网状内皮组织增生症病死率为4．4％～6．7％。应加强疫苗免疫，加强管理，减少病原，减轻危害。Epidemiological investigation on avian infectious tumor diseases in North Part of East China was performed by PCR method. 600 samples from asymptomatic chickens and 200 samples from symptomatic chickens was collected for the investigation, covering Langya laying hen, Hyline chicken, AA broiler and Avian broiler chicken.The result showed, Marek＇ s disease infection rate was 3.3% to 4.4% in asymptomatic chickens and mortality was 70.9% to 78.3% in symptomatic chickens; Avian leukosis infection rate was 8.3% to 11.6% in asymptomatic chickens and mortality was 4.4% to 6.6% in symptomatic chickens; Reticuloendotheliosis infection rate was 4.3% to 5.5% in asymptomatic chickens and the mortality was 4.4% to 6.7% in symptomatic chickens. Vaccination and management should be strengthened to reduce hazards resulted from tumor diseases in avian flocks.
